5.1.3 MIDI PROGRAMMING TAB
This tab is used to program the FW-1884’s control sur-
face in MIDI CTL mode. For detailed information on
using this function, please refer to section 4.2, “MIDI
Control Mode – (General Notes)”.
Here’s a quick scenario: Enter MIDI program-
ming mode … firmware sets subcode quadlet to “start
of programming” command, “0xC0000080”.
The host software starts up the MIDI Prog tab of the
control panel, with everything blank/grayed-out.
Now press the MUTE2 key while in Bank2 on an ES
unit, and the subcode quadlet is written as
“0x09414CE7”.
The host driver senses the change in the subcode qua-
dlet and the control panel displays its programming
information, something like:
Now if you click the “up” arrow next to the channel
number, the control panel updates to:
An asynchronous quadlet write is sent with a value of
“0x09414DE7”.
When you exit MIDI programming mode the subcode
quadlet is set to “0xC0010080”.
The host software detects the subcode change and
blanks/grays-out the MIDI Prog tab.
